Who We Are
Founder and President – Mark Gutshall
Mark Gutshall is the Founder and President of RiverStewards Collaborative. He is a professional wetland scientist (PWS), a licensed Pennsylvania charter boat/fishing guide (permit #767) and founder of LandStudies, Inc. a recognized leader in the field of environmental restoration and land planning. He has more than 35 years’ professional experience in designing, permitting, and constructing ecological restoration projects in the mid‐Atlantic region. During that time, he also founded Octoraro Native Plant Nursery, a wholesale source of native woody plants (1990).
His diverse professional background emphasizes land stewardship and community‐based planning, which he has applied to numerous projects in watershed planning, open space planning, stream corridor restoration, flood reduction and stormwater management, habitat improvement, and wetland creation.
Mark researches and advocates pioneering land management techniques that are functional, cost effective, and environmentally beneficial. He has been a leading voice in the acceptance of “legacy sediments” along stream corridors as a major contributor of sediment and nutrient pollution in waterways throughout Pennsylvania.
He also has been a groundbreaker in adopting regional or watershed‐wide natural resource management as an effective way to create partnerships among private, public, regulatory, non‐profit, and educational interests.
